hello scwalsall
unfortunately this isn’t possible.
Occasionally I use my private login on an Android TV at my workspace. So far, I always had to login when I used it. The credentials never got stored for long (login on the same day worked). It’s different on a web browser, they store the credentials and will always sign on automatically. You might have luck and the login info wasn’t saved for long.
But to be sure, you might want to change your password. Even if your credentials were stored, they can’t be used anymore.
